“…While we currently lack data on the aloes, stonecrops, and asclepiads, every arid-adapted succulent lineage investigated thus far has followed a similar tempo of evolution: Although the origins of a pronounced succulent syndrome in these groups vary widely between ≈40 and 10 Ma, they all share a single timeframe of extensive global diversification in the late Miocene-Pliocene. Studies of other desert (nonsucculent) plants from various regions have also demonstrated a similar pattern of recent radiation (17)(18)(19)(20). The simultaneous diversification of arid-adapted lineages provides a general insight into the history of the world's arid regions, which has been limited by a bias against fossil formation in dry environments.…”

The cacti are one of the most celebrated radiations of succulent plants. There has been much speculation about their age, but progress in dating cactus origins has been hindered by the lack of fossil data for cacti or their close relatives. Using a hybrid phylogenomic approach, we estimated that the cactus lineage diverged from its closest relatives ≈35 million years ago (Ma). However, major diversification events in cacti were more recent, with most species-rich clades originating in the late Miocene, ≈10-5 Ma. Diversification rates of several cactus lineages rival other estimates of extremely rapid speciation in plants. Major cactus radiations were contemporaneous with those of South African ice plants and North American agaves, revealing a simultaneous diversification of several of the world's major succulent plant lineages across multiple continents. This short geological time period also harbored the majority of origins of C 4 photosynthesis and the global rise of C 4 grasslands. A global expansion of arid environments during this time could have provided new ecological opportunity for both succulent and C 4 plant syndromes. Alternatively, recent work has identified a substantial decline in atmospheric CO 2 ≈15-8 Ma, which would have strongly favored C 4 evolution and expansion of C 4 -dominated grasslands. Lowered atmospheric CO 2 would also substantially exacerbate plant water stress in marginally arid environments, providing preadapted succulent plants with a sharp advantage in a broader set of ecological conditions and promoting their rapid diversification across the landscape.climate change | paleobotany | CAM photosynthesis P lants are generally classified as succulent when they exhibit pronounced water storage in one or more organs. High degrees of succulence are most often associated with a suite of other characteristics that together confer survival in water-limited environments. This "succulent syndrome" usually includes a shallow root system that permits rapid uptake of unpredictable precipitation; a thick, waxy cuticle that prevents excessive water loss; and Crassulacean acid metabolism (CAM), an alternative photosynthetic pathway that allows plants to uptake atmospheric CO 2 at night when water loss is minimized (1). Although some 30 plant lineages have been classified as succulent, only a small subset of those are species-rich and ecologically important elements of arid and semiarid ecosystems worldwide. These lineages include the ice plants (Aizoaceae, ≈2,000 spp), the spurges (Euphorbia, ≈2,100 spp., ≈650 of which are succulent), the stonecrops (Crassulaceae, ≈1,400 spp.), the aloes (Aloe, ≈400 spp.), the agaves (Agave, ≈200 spp.), the stapeliads and asclepiads (Apocynaceae-Asclepiadoideae, ≈3,700 spp., ≈1,150 of which are succulent) and especially the cacti (Cactaceae, ≈1,850 spp.) (2).The cacti represent the most spectacular New World radiation of succulent plants. Most cacti exhibit a highly specialized life form, with extremely succulent, photosynthetic stems and leaves that have been mo...

“…Despite these advances, many cases of non-monophyletic genera revealed in recent phylogenies remain to be fully resolved. There is evidence to suggest that several important genera are, or may be, non-monophyletic, in particular Piptadenia (Jobson & Luckow, 2007), Prosopis (Catalano & al., 2008); Albizia Durazz and Archidendron F.
